(CL..lim-aio)l 4 Claims..

This invention. relatesto` doors,A and more particularlyto doors of the all-weather type for use with the. usual. doors used. in dwellings.. although. certain features. of theinveutionare suitablefol'. use .in bathroom. dQOrs and Vother doors.

one object of'mylinvention is torrovide a door o f the type referred-,to wherein panelsthat comprise fly screen, glass, and sheet metal Acan readily be substituted for one.. another, to, suit seasonal conditions,.simply by ,the use of loclingstripsor bars that can readily be slidinto and-out of panelretaining position.

Another object .of my invention, is V'to-provide .a door'of the type vvreferred. to which is of lighter weight than doors -1 of conventional form and which is, nevertheless, of adequate strength. and durability.

Some of theformswhieh my invention may take are shown yinthe.accompanying drawings.. wherein Figure 1 iszan outer face` View of. a door; Fig..2 is an enlarged-vviewtaken on anyof the lines. I'III of Fig. l.; Fig., 3 Ais an enlarged view taken on the line III-:III ofFig., 1; Figs.. 4.and 5 are edge and faceyiews, respectively, of =.a. form .ofv

Fig. 1Q; Fig. 7 is-an enlarged'view takenon the,

line VII-VII of Fig. 1; Fig.. 8. shows amodiiication of the rail of Fig. 7 9 shows still another modification thereof; Fig. 10-is an enlarged face view of one of theorners ofthepanel frame that holds a fly screen; Fig. 11 is a view showing the inner face of the door of Fig. 1; Fig. 12 is an enlarged View showing a modification of the loweru portion of the door of Fig. 1 and the lrelation of the outer door to the inner door, and Fig. 13 is an enlarged sectional View showing one of the breather openings in the uppermost rail of Fig. 14.

The structure comprises stiles l having rails I6 and I'l welded thereto in mitered relation at the upper and lower ends of the. stiles. Intermediate rails lfand 20 (Figsg andy?) are welded at their ends to the stiles I5. These parts are preferably made of light weight metal such as aluminum.

Each of the stiles and rails I5-I 6-1 'l has a flange 2l to provide an angular seat for a panel frame such as the frame 22 of Figs. 1, 2 and 10. The screen frame 22 is formed of rectangulariyarranged bars 22 welded together and having grooves to receive clamping rods 23 that will hold a Wire cloth or screen 24 at its four edges.

The corners of the frame 22 are reinforced by angles I8, as shown more clearly in Figs. 6 and 55 10, such;barsnuelrtting Withintheansle ai. each. corner. anri-..beir1e.

Thelowermost panellframe32 of the door mayv suitably be of sheet metal held in a frame formed of rectangularly-arranged bars-33-that may suitably beof l substantially-the same formas the screen frame bars Y2,2. Theframe vformed by the member `33v is releasably held at its upper edgein 'k against the stilles and the bottom rail Il by locking bars such as 25,

As explained.. above., panel; Substitutions may readily be made so that glass, screen or flat sheets can be used in any or all of the various panel areas. In Fig. 8 is shown a modied form of intermediate rail 3l which is especially suitable where a, plurality of sheet metal panels 38 are desired, or Where a combination of sheet metal and screen panels are desired. The frames 39 for these panels Will be held in place by locking bars 4|, at their horizontal edges, while their vertical edges Will be held in place against the anges 2| of the stiles by locking bars 25. It will be seen that the rail 20 of Fig. 7 can also be utilized to The vertical hold a screen frame or a sheet metal panel frame instead of the glass.

In Fig. 9 is shown a modication of the rail of Fig. 8. In this arrangement, a rail 42 has a closure plate 43 held in place by a screw fnl. The utility of this arrangement resides in the fact thatl the welds which joint the ends of the rail to the stiles l5 can be made at the inner surfaces of the rail, therefore having them in concealed locations. After completion of the welds, the cover plate 43 will be attached.

Referring now to Fig. 12, I show an air-circulation opening for the door frame, whereby, in cold weather, there may be some circulation of air between this door and the regulation door indicated at 45, when this door is being used as a storm door, to thereby avoid condensation of moisture or sweating ou the opposed faces of the doors. In this arrangement, a rail 4E is substituted for the rail 28 of Figs. 1 and '7 and the lower panel frame 33 is spaced below the rail 46 to provide a slit ll through which outside air may circulate to somewhat equalize temperatures at the inner and outer faces of the storm door. The frame 33 will rest upon and be supported by the bottom rail l' and will be held in place by the locking strips 25. A strip 48 is slidably supported on the upper bar of the frame 33 and is frictionally held in vertically-adjusted positions by a headed pin or rivot 49, the strip being provided with elongated holes 50 (Figs. 5 and 12). The ends of the strip 48 are slidable in the vertical grooves of the stiles l5.

Referring now to Figs. 1, 11 and 13, I show breather openings through the door frame to permit of movement of air through the door, as when there is no screen panel in the door. These breather openings allow such movement of air that there will be no pressure or suctional resistance to movement of one door when the other door is in its closed position.

To this end, openings are provided through the outer walls of the cross bar IS, the openings having eyelets 52 to give them a nished appearance, and having screens 53. At the opposite face of the door, holes 5d are provided through the inner wall of the rail l1. The stiles I5 and the rails` I6 and l1 being hollow, there will be movement of air through the stiles and the holes 52 and 54 when pressure or suction is created between the F inner and outer door through relative movements of the doors.

I claim as my invention:

l. A door comprising a frame having side stiles of hollow sheet-metal construction, rails connecting the stiles adjacent to their upper and lower ends, flanges on the inner edges of the stiles Iand the rails, adjacent to one face of the frame and extending toward the panel area, to thereby form angular seating surfaces of elongated form, there being grooves formed in the inner edges of the stiles and the rails, adjacent to the other face of the frame and parallel to the said anges, and locking bars insertible into the grooves but partly protruding therefrom, to retain a panel-like element in position against the iianges, there being breathing openings through the outer and inner walls of the frame 'and having communication With one another, through the hollow spaces in the frame.

2. A door comprising a frame having side stiles of hollow sheet-metal construction, rails connecting the stiles adjacent to their upper and lower ends, flanges on the inner edges of the stiles and the rails, adjacent to one face of the frame and extending toward the panel area, to thereby form angular seating surfaces of elongated form, there being grooves formed in the inner edges of the stiles and the rails, adjacent to the other face of the frame and parallel to the said flanges, and locking bars insertible into the grooves but partly protruding therefrom, to retain a panellike element in position against the flanges, there being breathing openings through the outer and inner walls of the frame and having communication with one another, through the hollow spaces in the frame, the outer opening being located adjacent to one end of the frame and the inner openings located adjacent to its other end.

3. A door comprising a frame having side stiles, rails connecting the stiles adjacent to their upper :and lower ends, an intermediate rail connecting the stiles, panel frames secured to the stiles and the upper and lower rails, the upper edge of the lowermost lpanel having one of its horizontal edges spaced from one of the rails, and a sealing strip cm'ried by the door and slidable thereon to close and open the said space.

4. A door comprising a frame having side stiles, rails connecting the stiles adjacent to their upper and lower ends, an intermediate rail connecting the stiles, panel frames secured to the stiles and the upper and lower rails, the upper edge of the lowermost panel having one of its horizontal edges spaced from one of the rails, and a sealing strip carried by the door and slidable thereon to close and open the said space, the door frame being Ihollow and having breathing openings therein that open to the inner and outer faces of the frame, the outer openings being adjacent to one end of the door and the inner openings adjacent to its other end.
